The Mossad is the national intelligence agency of Israel, responsible for human intelligence collection, covert action, and counterterrorism. It is one of the main entities in the Israeli Intelligence Community, along with Aman (military intelligence) and Shin Bet (internal security). Mossad is headquartered in Tel Aviv and has an estimated 1,200 personnel. Its focus is on Arab nations and organizations throughout the world, and it is responsible for the clandestine movement of Jewish refugees out of Syria, Iran, and Ethiopia. Mossad agents are active in the former communist countries, in the West, and at the UN. The agency uses both HUMINT (human intelligence) and SIGINT (signals intelligence) and has been involved in pursuing Nazi war criminals, culminating in the capture of Adolf Eichmann and bringing him to justice in Israel. Mossad has an annual budget of about $3bn and 7,000 staff, making it the second-largest espionage agency in the Western world after the CIA. Despite its reputation as one of the best intelligence agencies in the world, Mossad has faced criticism for intelligence failures, such as its failure to detect Hamas surprise attack on Israel in 2023.
